Method for spatial 3d stereoscopic intraoral camera

A method for creating intraoral cavity spatial 3D images for stereoscopic rendering and display comprising the steps of:

• providing a processor and memory for executing programmed logic;
• having logic containing a wireless component working with the processor and memory for connecting with external devices and remote processing;
• integrating dual side-by-side camera sensor CCD subassemblies with the sensor subassemblies each having an optical path through a lens disposed to direct light to a CCD embedded in a daughter board;
• providing focusing control with a CCD imaging chip converging optical paths of duel side-by-side subassemblies by tilt, tilt range of between 1° to 5° off the surface mount plane, or shift, shift gap symmetrically with the duel subassembly centerline of between 0.5 mm and 5.0 mm, to achieve the stereoscopic convergence;
• operatively mounting and integrating the CCDs on daughterboards with a lens focal gap of between 0.01 and 3.0 mm each;
• surrounding each subassembly with programmable logic for frequency sweeping through an array of LEDs with source light spectrum spanning from UV to Near Infrared;
• having the LED array source emit light so that it is disposed to enter a beamsplitter in the subassembly adjacent to the lens;
• refracting beamsplitter incoming light from the LEDs to a reference leg optical path normal to the incoming light and with a mirror on the reference path end reflecting reference beam back to beamsplitter and bending toward the subassembly lens;
• positioning the LED between the beamsplitter mirror and the lens centerline in a symmetric pattern LED array for emitting Near Infrared light from a transparent surface mounted LED package;
• having the beamsplitter aligned in a straight through optical path for illumination and reflected image light recombining with reference light on route to the subassembly lens;
• mounting each subassembly surface on a motherboard supporting other electronic components for processing the CCD signals and LEDs emissions, and
• providing software instructions in the form of device logic stored in memory for enabling the device, under control of the processors to format the CCD signal images for wireless transport to remote processing system for storage and rendering in 3D Line Sequential Left-Right Multiplexed Spatial Stereoscopic format,
• whereby spatial 3D intraoral images are converged, captured and bundled by the duel subassemblies for processing and display in stereoscopic rendering and viewing.
